RP/0/RSP0/CPU0:router (config-l2vpn-xc-p2p-pw)# source 1111:3333::abcd
Configures the source IPv6 address of the pseudowire.
Step 9 l2tp static local cookie sizesizevaluebytes
Example:
RP/0/RSP0/CPU0:router (config-l2vpn-xc-p2p-pw)# l2tp static local cookie size 8 value 0xabcd 0x1234
Configures the static local cookie size settings for the L2TP pseudowire.
Step 10 l2tp static remote cookie sizesizevaluebytes
Example:
RP/0/RSP0/CPU0:router (config-l2vpn-xc-p2p-pw)# l2tp static remote cookie size 8 value 0xcdef 0x5678
Configures the static remote cookie size settings for the L2TP pseudowire.
Step 11 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.

Configuring L2TPv3 over IPv4 Tunnels
L2TPv3 over Ipv4 Tunnels is supported only on layer 2 transport sub-interfaces and not on physical interfaces.
When an untagged traffic has to be sent through L2TPv3 over IPv4, create a sub-interface with encapsulation
as untagged.
This example shows how to create a sub-interface with encapsulation as untagged:
interface TenGigE0/3/0/1.123 l2transport
encapsulation untagged
